+- Always configure `output` with an existing dataset; the runner requires it even though the descriptor marks the role optional.
+- For the sender, either set `sender_column`, or set `use_sender_value=true` and `sender_value`, unless the selected mail channel already defines the sender.
+- For the subject, either set `subject_column`, or set `use_subject_value=true` and `subject_value`.
+- For the body, either set `body_column`, or set `use_body_value=true` and use `body_format` with `body_value` for plain text or `html_body_value` for HTML.
+- For `mail_channel`, call the `list_message_channels` tool with `integrationType=mail`. If several channels are available and the user did not identify one, ask which one to use.
+- Set `mail_channel` to the chosen channel id. Append `__WITH_DEFINED_SENDER__` when its `sender` is set or `useCurrentUserAsSender` is true.
+- If the user chooses to configure SMTP directly instead of using a DSS mail channel, set `mail_channel` to `__DKU__DIRECT_SMTP__`. When no DSS mail channel exists, leave it null.
+- When direct SMTP uses authentication (`smtp_use_auth=true`), set `smtp_user` and ask the user to set `smtp_pass` in the DSS recipe settings; both are required by SMTP login.
